The article analyzes the evaluations of students' parents, administrators, and teachers about the influence of family factors on the social adaptation process of secondary school students. The results show that parents, administrators, and teachers highly appreciate the influence of the family psychological atmosphere on the social adaptation process of students; students' parents highly appreciate the influence of parents' attention on their children, and administrators and teachers highly appreciate the influence of parents' educational style.

Anton Xemionovich Makarenko là nhà lý luận và thực tiễn xuất sắc của nền giáo dục xã hội chủ nghĩa. Ông đã vận dụng sáng tạo lý luận Macxit vào thực tế để rút ra những kinh nghiệm làm phong phú cho lý luận giáo dục xã hội chủ nghĩa nói riêng và giáo dục nhân loại nói chung. "Bài ca sư phạm" là một trong những tác phẩm tiêu biểu của A.X.Makarenko. Tác phẩm chứa đựng ý nghĩa giáo dục to lớn, đồng thời là một bài ca hiện thực, trữ tình, ca ngợi sức mạnh tốt đẹp của tập thể, mối quan hệ giữa lợi ích cá nhân với lợi ích tập thể, lợi ích của toàn xã hội

This paper presents a new method in controlling a parabolic trough solar collector system to improve the efficiency of the solar-to-thermal energy. It is designing an intelligent preprocessor using Hedge Algebra algorithm to calculate the setpoint for the control loop, in which besides the information about the trajectory calculated by a software, wind speed and fluid temperature of the collector are included. Moreover, this paper introduces a new simple flexible calculation tool which enables to calculate with a higher accuracy.

Background The evaluation of tools to accurately identify low birth weight (LBW) and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC) measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age. Materials and Methods An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8) were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared. Results 485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96–0.99), and performed marginally better than foot length (AUC 0.94, 95%CI 0.92–0.96). The optimal cut-points for measurements within 24 h of birth were ≤7.4cm for foot length; ≤30.4cm for chest circumference; and ≤ 9.0cm for MUAC. There was statistical evidence that anthropometric measurements taken within 24 h of birth were higher than measurements on day five (p
